If you're going to go that far, ditch 24 hours and go metric: 100 hours per day, etc. Minutes and degrees of longitude are a holdover from the ancient Egyptians who used base 60 numbers.
If you're going to do that, we need to make degrees and radians metric as well. Also, we might as well go ahead and slow down the revolutions of the earth so that there are only 100 per trip around the sun instead of 365.25 +/- iota. I would say speed it up to 1000 revolutions per year, but I actually need my days to be longer, not shorter. Our workload at my company requires the day to have at least 36 hours in it, so if the day was about 3 times longer, that would still allow some time to sleep as well.
